Jim follows the same wannabe bodybuilders in the gym who do more curls than a hair stylist... But why isn't he getting any bigger? Don't be like Jim and learn what really makes your arms bigger.

If you've been training like Jim and you are tired of not seeing any results, check out these 12 tips to build some massive arms.

Build Bigger Arms

#1 - Triceps vs Biceps

A common misconception about building big arms is that the bicep is the important muscle to train. Sure, having a nice bicep peak is nice, but if you are looking for the massive arms that make people stop what they are doing to look, you need to hit your triceps too.

Your triceps make up two-thirds of your arm, so why neglect them?

If you have a well-rounded workout, the pressing movements help hit your triceps, while the pulling exercises hit the biceps. The important part of your training comes after your main lifts; what do you do to train triceps and biceps afterward?

Do you have a specific arm day? Do you have an upper body/lower body split?

Whatever it is, be sure to put as much (if not more) emphasis on your triceps, while building strength and size in your biceps.

#2 - Quit Focusing Solely on Isolation Movements

Like I said earlier, your biceps and triceps both get worked on heavy compound movements.

If you skip the step of lifting heavy at all, the baby weights will keep you with baby arms.

Ronnie Coleman is right, everyone wants to be a bodybuilder, but nobody wants to lift this heavy (bleep) weight.

Any pressing movement incorporates your triceps. This means all of the benching and overhead pressing you do is helping build your arms.

#5 - Progressively Overload

Every time you go to the gym, you want to put time and effort into each set and each rep you do. Why do you do that exercise? What weight have you been using? Are you doing more reps or doing more weight each time?

You are progressively overloading your muscles, you strive to add reps or weight to your lift each time you step foot in the gym. No more of this, "I've benched 135 for 5 sets of 8 for the last 4 months" crap.

#6 - Try a Different Tempo and Rep Range

Many people in the gym do a simple 1:1 tempo, which means they spend the same amount of time on the concentric motion as they do on the eccentric motion. For bicep curls, about one second to curl it, one second to straighten your arm.

It's a simple protocol that works, but messing with your tempo can spark some gains you didn't think you could get.

Simply try changing your tempo to 2 or 3 seconds and notice the extra strain and stress on your muscle. The more microtrauma you cause to the muscle will cause it to grow even bigger.

Start with changing the tempo on one or two isolation exercises, and then gradually modify the rest of your training so that your eccentric part of the lift slows down.

Try changing your rep ranges from a normal 8-12 range to a heavy 3-5 rep or a high volume 15-20 reps. The small change can make drastic improvements to your arms.

#7 - Try Eccentric Only Training

Eccentric only training is unique because you can generally use more weight on the eccentric portion of a lift than a concentric.

Don't know what that means?

Go over to the preacher curl station and grab your normal dumbbell. Do some reps to warm up and then choose a weight slightly higher than what you can normally rep out. Start with your arm in the curled position and slowly let the dumbbell down and straighten your arm.

You probably can't curl it back up, so use both hands and get back into position and go again. This eccentric only training works well as long as you use good form and practice safe lifting.

#8 - Use Different Grips

Just like on the bench press, using different grip widths can make a huge difference on how the muscle is targeted.

Never tried close grip bench press? Try them out and see how much your triceps scream.

Do you like to do barbell curls? Try moving your grip with in or out and feel the difference in how your muscles work together.

Instead of putting your hands directly in the middle of a dumbbell, try offsetting your grip and try different methods that work well for you.

Bonus - Lose That Fat

While this is the most effective way to make your arms appear bigger, it's not necessarily the best for building massive arms. Having 15-inch arms on a 120-pound frame may look good and all, but who doesn't want those 18"+ arms?

If you are already strong, lift consistently, and pack on some extra poundage, losing some of that weight will make your arms appear bigger, make you more vascular, and give you an overall better-looking physique.

Wrapping it Up

Sometimes a small change in tempo, rep range, or weight can make explosive growth in your arms. Take the time to eat right, train your entire body, choose quality exercises, and progressively overload.

Following these tips will help you get a better set of guns and can boost your confidence to get even bigger, faster, and stronger.
